Dear all,

I used the the 3 steps of longitudinal analysis explained in freesurfer longitudinal tutorial and need to compute the ratio Parenchyma/CSF for each of time points. Is this equivalent to compute the (total gray matter volume + total cortical matter volume)/CSF from aseg.stats file ?

Thank you, Mahmoud
